At some point today, we'll be moving our site from one server to another (from Indiana to California; it'll be a long flight for the data!). Because of this, you might end up finding yourself stuck on the old site for a couple of days, while the DNS settles. To see whether or not you're on the old or new server, you can check the source code for the site (Ctrl + U in most browsers) and look near the bottom. There will be a message like this:

OLD TECHGAGE SERVER

or

NEW TECHGAGE SERVER

I think that's self-explanatory. If you find yourself stuck on the old server tomorrow (Monday+), I'd recommend trying to force a flush of your DNS.
